The Crumpled Package is an Item exclusive to Don't Starve Together, introduced in A New Reign. It can be obtained by Fishing in the Lake at the Oasis. Similar to Bundled Supplies, Crumpled Packages contain items, that will be dropped when opened.
Most packages contain Trinkets, thus making them renewable. A special Trinket, the Beach Toy can only be acquired by finding it inside a Crumpled Package. However, it may also contain the rare Blueprints for the Fashion Goggles, Desert Goggles and Potted Succulent, as well as various other Blueprints.
